At what temperature should a boneless prime rib be cooked at?

There are two ways to cook prime rib roasts. If you choose to cook it low and slow you will want to set your oven to 350 degrees Fahrenheit and cook it for 17-20 minutes per pound. If you want to cook it a higher temperate for a shorter period of time it is recommended that you set the oven to 450 degrees Fahrenheit and allow 13-15 minutes per pound.
